A device for treating a target area of a vessel wall of a vessel within a human or animal body, the device comprising: an expandable portion for radially expanding the device from a contracted configuration allowing travel within the vessel to the target area to an expanded configuration allowing treatment of the target area; a protective sheath stretch-fitted over the expandable portion to exert a compressive force on the expandable portion for radially contracting the device from its expanded configuration to its contracted configuration, and for exerting a compressive force on the expandable portion in its contracted configuration; and at least two spaced apart treatment implements extending radially outwardly from the expandable portion, wherein in the device's contracted configuration the implements are shielded within the protective sheath, and in its expanded configuration the thickness of the sheath decreases to expose the implements for contact with the target area of the vessel wall. A protective sheath for fitting to a device for treating a target area of a vessel wall of a vessel within a human or animal body, a balloon catheter sheath loading device and method for loading a tubular sheath onto a balloon catheter, and a method of treating one or more target areas of a vessel wall within a human or animal body are also disclosed.

A floorboard assembly comprises first and second solid wood floor boards (10) and (12). The first floor board (10) has a tongue (14) extending longitudinally along a first side thereof. The second floor board (12) having a groove (16) extending longitudinally along a second side thereof. The groove (16) has a width defined between a top lip (22) and a bottom lip (24). The tongue (14) is insertable in a tight fit manner in the groove (16) to prevent translational separation of the boards (10, 12) in a common plane thereof. A clearance (26, 26′, 28, 32, 32′, 32″, 36 and 38) is provided between the tongue (14) and the groove (16) at one of a tip portion of the tongue (14) and an outermost portion of the top and bottom lips (22, 24) of the groove (16). The clearance (26, 26′, 28, 32, 32′, 32″, 36 and 38) is configured to allow angular withdrawal of the tongue (14) from the groove (16) by manually pivoting the first and second floor boards (10, 12) towards one another in one of an upward and a downward direction.

The present invention is directed to a measuring unit, for measuring characteristics of a sample liquid, comprising a support member, having at least one upper bearing arm, with an upper bearing unit, at least one lower bearing arm, with a lower bearing unit, and a base, for being attachable to a respective measuring system; a shaft, having shaft toes and being rotatably supported about a rotation axis, by said upper bearing unit, and said lower bearing unit, wherein said upper bearing unit, said lower bearing unit, and said shaft toes form toe bearings, respectively; an interface member, having a detecting element, and a drive element, said interface member, being fixed on said shaft, and being connected to a coupling shaft, with a probe connector section, for measuring characteristics of said sample liquid; wherein said interface member, and the coupling shaft, are coaxially aligned with said shaft.

The disclosure provides an adjustable optical lens comprising a membrane, a support for the membrane, a fluid between the membrane and the support, an actuator for deforming the membrane, and a rigid ring connected to the membrane for moving with the membrane for ensuring that a section of the membrane surrounded by the rigid ring has a defined circumference.

A shelf assembly includes a panel having an edge and two opposed spaced apart sides extending from the edge. A light source positioned at or adjacent the edge of the panel, which selectively generates light and directs the light in an initial direction into the panel. In addition, the panel is adapted to redirect the light from the initial direction to an illumination direction through at least one of the sides of the panel.

A wheel support bearing assembly for rotatably supporting a wheel 13 relative to a vehicle body structure 12 includes outer and inner members 1 and 2 with dual rows of rolling elements 3 interposed therebetween. An electric generator 4 for generating an electric power as one of the inner and outer members 1 and 2 rotates relative to the other of the inner and outer members 1 and 2 is utilized. The electric generator 4 includes a coil / magnetic element combination 17, including a ring member accommodating a coil therein, and a multi-pole magnet 18. A signal outputted from the electric generator 4 and indicative of the number of revolutions of the wheel 13 is transmitted wireless by a transmitter 5. This transmitter 5 may be an annular transmitter.

A radio-frequency power amplifier with envelope tracking, comprising: a power RF amplifying device for amplifying a RF signal; and a switching DC / DC converter, comprising a switching device and a rectifying device, for providing said power RF amplifying device with a DC power supply at a. voltage level proportional to an envelope of said RF signal; wherein said switching device is a RF power transistor; characterized in that said rectifying device, and preferably also said power RF amplifying device, is also a transistor of a same technology, connected as a two-terminal device. Preferably, said power RF amplifying device is also a transistor of said same technology. A low-pass filter can also be provided for reducing the bandwidth of the envelope signal on which the PWM signal driving the DC / DC converter depends.
